Special Issue Information

Dear Colleagues,

Buildings account for one-third of energy use and a quarter of greenhouse gas (GHG) emissions in the world. They are estimated to make up 24% of baseline energy use by the end of the 21st century due to unmitigated climate change. Building fabrics (wall, roof, and floor) are mainly responsible for 50–60% of heat transfer in buildings. However, lightweight construction materials are being developed to reduce heat transfer loss through building envelope, but they exacerbate summertime overheating under extreme heatwave periods. Summertime overheating enhances heat-related mortalities and morbidities in buildings. Therefore, there is a need to mitigate adverse health and environmental impacts in buildings by developing sustainable construction materials, designing energy-efficient design and retrofit strategies, and alternative passive measures.

This Special Issue aims to contribute to new research developments in sustainable construction materials, novel energy-efficient designs, environmentally and economically feasible retrofit and refurbishment strategies, and advanced passive measures for sustainable built environment deign under different climate conditions. This Special Issue welcomes submissions focused on the following topics:

  1. Lightweight construction materials (cementitious and geopolymer composites and carbon-negative concrete);
  2. Building insulation materials for heat resistive infrastructures;
  3. Phase change materials for heat resilient buildings;
  4. Reflective coating materials for mitigating indoor and outdoor thermal comfort;
  5. Recycled materials for sustainable buildings;
  6. Advanced coating materials for window glazing;
  7. Building envelope design (opaque and transparent);
  8. Building retrofit and refurbishment strategies;
  9. Heating, ventilation, and air conditioning system design and analysis;
  10. Green building technologies;
  11. Energy analysis and thermal comfort assessment;
  12. Life cycle cost analysis;
  13. Life cycle assessment;
  14. Building information modelling;
  15. Climate change and extreme heat waves.

Today, bio-sourced materials represent an important technological field of study, as they could sink atmospheric carbon dioxide into buildings. Little-processed construction materials would also reduce the environmental impact of the construction sector, which emitted more than 2.9 Mt of CO2 in 2020. Hemp-lime is a material that meets both these requirements. It is an insulating mix that can take different forms and be used in various parts of a building. The challenge is providing it with enough mechanical strength to make it loadbearing, at least to some extent. This research focuses on the construction and monitoring of a pointed arch, based on a previous experimental hemp-lime construction at Cardiff University in 2009, under the direction of architect David Lea. Since 2022, such an experiment on a possible loadbearing hemp-lime mix is being repeated at the Politecnico di Torino as part of a wider project called “experimental pavilions of vegetarian architecture”. The design and numerical analysis of the Cardiff prototype led to the modification of both the geometry and the composition of the mix using only pozzolanic air lime as the binder. The construction of the arch ended in December 2023. Observing the thermo-hygrometric conditions of this hemp-lime mix once in place is the main purpose of this article. A strong correlation is revealed between outdoor conditions with temperature and moisture content in the core of the arch. Building a full-size outdoor prototype allows for the avoidance of mathematical correction to the results obtained and allows the assessment the mix’s resistance in relation with environmental conditions. Due to some similarities of nature and function between lime and cement, many studies of lime mixes do not exceed a duration of 28 days, which cannot be considered the appropriate observation time for its curing. Therefore, we analysed this lime-based material for around 6 months, according to its own temporality and chemical kinetics. Through continuous monitoring at 10-min intervals, it was possible to highlight several significant aspects of rammed hemp-lime. The results show that the temperature within the mix is influenced by the outside temperature, but the sun exposure of certain areas drives up the corresponding temperature values more rapidly. Furthermore, while the absorption of water in the form of vapour is very rapid, desorption takes longer, as does re-establish a balance between the material and its context. Finally, solar exposure affects particularly 30-cm-thick elements, while elements that are 60 cm thick are not affected in the short term but only in long-term exposure conditions like season changes.
